STEAM -TRAP.

SPECIFICATION forming part of Letters Patent No. 253,670, dated February 14, 1882. Application -filed December 1, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEORGE B. BOOMER, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Steam-Traps, of which the following is a specification.

This invention relates to that class of steam traps embodying an open -mouthed float, receiving the water of condensation from the steam-pipe and acting as a valve to open and close the water-escape orifices according to its position .,v.

Th'fs'invention consists in a float constructed with aneck having lateral water-escape orifices which are diametrically opposite to each other,

in combination with a casing constructed with a neck receiving the neck of the float, and having lateral water-escape orifices which are diametrically opposite to each other and in correspondin g vertical planes to the orifices of the float, and a means for guiding the float in a vertical plane, so that in a certain position of the float its orifices register with those of the casing, and the water in the float is allowed to escape.

It also consists in making the casing T- shaped and connecting the lower part of its neck with the upper part or head thereof by a water-way, as hereinafter more fully set forth.

Thisinvention is illustrated in the accompanying drawings, in which Figure 1 represents a vertical central section. Fig. 2 is a similar section taken at a right angle to Fig. 1. Fig. 3 is a horizontal section on the line a; m, Fig. 2. Fig. 4 is a like section on the line y y of Fig.2.

Similar letters indicate correspoudin g parts.

The letter A designates the open-mouthed float, and B the casing, both constructed with a neck, A or B, and in the example shown in Figs. 1 to 4, inclusive, the neck of the float is fitted or ground into that of the casing. The casin g B is placed on a suitable base, and to the top thereof is connected a steam-pipe, 0, leading from the apparatus which is to be cleared of the water of condensation.

The letter (1 indicates the orifices of the float, and 6 those of the casing, these orifices being formed in the lateral portions of the neck A or B diametrically opposite to each other, and those of the casing being in corresponding vertical planes to those of the float.

In the example shown in Figs. 1 to 4, pipes e are connected to the orifices of the casing for conduct-ing the water to the desiredplace, and, if desired, these pipes may be joined together, so as to have a common outlet.

The float-guide is composed of a screw-stem, f, passing through the side of the casing, and engaging a U-shaped strip, g, attached vertically to the side of the float; but the guide can also be formed in other ways, which will readily suggest themselves to a skilled mechanic. In applying the trap to use, water is poured into the casing A in sufficient quantity to raise the float B to such a position as to bringits orifices 01 above the easing-orifices 6, thus closing up the latter, a suitable stop being used, if desirable, for determining the up per position of the float. The water of condensation issuing from the steam-pipe 0 drops into the float A through its open mouth, thus gradually increasing the weight of the float, and when its weight reaches such a point as to overcome the buoyant power of the water in the casing the float sinks down until its orifices d meet or register with the casing-orifices e, whereupon the water escapes from the float and the latter is permitted to rise, again closing the casing-orifices. If by the condensation of the steam entering the casing the level of the water supporting the float B therein rises to the top of the float, it si mply overflows into the latter and escapes with its other or remaining water. When the neck A of the float is fitted into the neck B of the casing, as shown in Figs. 1 to 4, the casing is formed with a head, B imparting thereto an approximately T shape, and a water-way, h, is used to connect the lower part of the neck with the head of the casing. In the example shown this way h is formed of a pipe exterior of the casing; but it can also be formed in the wall of the casing.

A trap has heretofore been formed of a cas ing having a central neck with water-escape orifices, and of an open-mouthed float fitted on such neck by means of a central imperforated collar, which slides above or below the orifices of the casing to open them. As will be seen, such trap differs in construction from mine; and the advantages of my trap are that by the arrangement of the water-escape orifices in the neck of both the float and the casing the neck' of the float can be made of sufficient length to afford a good bearing thereto.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a steam-trap, of the T-shaped casing having its neck provided with lateral water-escape orifices which are diametrically opposite to each other, and also provided with the steam-pipe opening into the upper portion ofsaid casing, the open-mouthed T-shaped float, arranged to receive the water of condensation from the steam-pipe, and constructed with a neck, A, fitted in the neck B of the casing, and provided with lateral waterescape orifices d, substantially as shown and described.

2. The combination, substantially as hereinbefore set forth, of the T-shaped casing having its neck provided with lateral water-escape orifices which are diametrically oppQsite to each 20 a steam-pipe, the open-mouthed float, arranged to receive the water of condensation from the said steam-pipe, and constructed with a neck fitted into the neck of the casing, and provided 25 with lateral water-escape orifices which are diametrically opposite to each other and in corresponding vertical planes to the orifices of the casing, the water-way connecting the lower portion of the neck with the head of the casing, 0 and the float-guide, for the purpose specified.

In testimony whereof I have hereunto set my hand and seal in the presence'of two subscribing witnesses.

GEORGE E. BOOMER.
